Some testers with smaller heads and bodies reportedly had trouble keeping Apple's Vision Pro headset on for more than 30 minutes

• Apple's forthcoming Vision Pro headset reportedly posed a challenge for some smaller testers.
• Testers with small heads and bodies had trouble keeping it on more than 30 minutes, Bloomberg reported.

The Apple Vision Pro headset is set to launch next year in the US, but so far some physically smaller testers have reportedly found the high-tech goggles a little trickier to keep on for extended periods of time.

Those with smaller heads and bodies who tested out the $3,500 device found it was hard to keep it on for more than 30 minutes, according to a new Bloomberg report.

The company has been working on solutions, including a second support strap, which was briefly shown off in the device's announcement but has yet to have its design finalized, according to the report.

Representatives for Apple did not immediately respond to Insider's request for comment ahead of publication.

The consumer electronics giant is planning to launch the devices "early" next year, involving appointments for those coming to stores to buy it, Bloomberg reported.

The device, which promises an experience that combines the real and digital worlds, comprises a glass window held by a metal frame, and a component Apple calls a "Light seal" that's designed to keep out external light and helps the device fit snugly on the wearer.

Components like that are expected to be customized to the user's face to help make sure the fit works.

The complicated nature of the device and its technology is also reportedly leading to a slowdown in producing them, according to the FT, which reported that a manufacturer in China is planning to make less than 400,000 of the devices next year.
